In December 2022, uAvionixannounced its updated product line for unmanned aerial systems (UAS) beyond visual line of sight (BVLOS) command and control (C2). The SkyLine C2 management platform and muLTElink airborne radio systems (ARS) are designed to integrate, which enables a self-healing C2 network capable of both path and link diversity. This eliminates lost-link possibilities over broad terrain and altitude ranges.

MuLTElink ARS consists of two models — muLTElink915 and muLTElink5060, the core of the uAvionix C2 system. The muLTElink915 model combines globally licensed aviation LTE, enhanced with frequency hopping 902–928 MHz industrial, scientific and medical frequencies capability. The muLTElink5060 model combines global LTE with aviation-protected 5,030–5,091 MHz C-band for customers holding C-band licenses for control and non-payload communication (CNPC) operations.
Each muLTElink model allows up to one external CNPC radio to be optionally connected to allow simultaneous use of all three frequency ranges, higher power C-band operation or future radio integrations.
UAvionix updated its previous line of microLink and SkyLink ARS radios and relaunched them under the SkyLink ARS banner. Each SkyLink ARS can operate as a point-to-point radio or integrate with muLTElink and SkyLine for managed C2 operations. SkyLink915micro, formerly named microLink, offers a robust form factor and Lemo connector for UAS requiring hardened installations.
SkyLink5060micro and SkyLink5060 offer 100 mW and 10 W 5,030–5,091 MHz aviation protected C-band CNPC options.
Both platforms meet standards set by RTCA DO-362A and the U.S. Federal Aviation Administration’s draft Technical Standard Orders-C213a and may receive similar validated orders through other global aviation regulators.

As most GNSS industry insiders already know, the Federal Communications Commission (FCC) has licensed adjacent GNSS L1 protection frequencies to Ligado Networks (formerly Lightsquared) for its nationwide 4G-LTE network.
Many objections emerged as expected this second time around from government agencies, industries and U.S. forces — yet the roll-out is still underway, pending actual interference occurring. This all in an attempt to find communications bandwidth for many emerging commercial radio applications.
Now, as 5G C-Band 3.7–3.98 GHz wireless phone networks begin their FCC approved roll-out, the Federal Aviation Administration (FAA) has apparently lodged an unanticipated objection on the grounds that cross-interference could compromise aircraft radar altimeter and wireless communications that operate at 4.2 to 4.4 GHz in the C-band.
While 5G wireless has already been operating in many parts of the world without reports of interference with aircraft systems, the FAA appears to be taking a more conservative approach to how aviation in the United States should co-exist with the new 5G phone wireless system. The FAA has proposed imposing an exclusion zone around airports for 5G wireless networks — which apparently have already been operating with reduced power in these areas — until cooperative operation has been proven.
Now along comes a new C-band wireless network (SkyLink) aimed at providing high-integrity unmanned aircraft systems (UAS) command and control (C2). The SkyLink company uAvionix has also developed a C-band Control & Non-Payload Communications (CNPC) radio for UAS applications.
Together with Thales, uAvionics recently tested its radio with its SkyLink radio network. The network has been qualified in accordance with the RTCA DO-377 standard for a network management system that monitors network and radio link health, and the radio has been developed to the draft FAA Technical Standard Order (TSO) C-213A to support critical UAS operations.
The network uses new DO-362A-compliant SkyLink C-band radios, integrates certifiable aviation-grade hardware and software, uses frequency agility, and provides critical fault monitoring and control capability. The objective is to obviate the loss of the C2 link with the vehicle, and thereby enable beyond-visual-line-of-sight (BVLOS) operations without an FAA waiver.
It’s unclear whether the emergence of the C-band network — approved by both the FAA and FCC — will play a role in the current phone network interoperability issue. However, uAvionix reports that several sites in the United States and offshore are either rolling out C-band SkyLink networks or evaluating doing so.
North Dakota already has an ISM-band SkyLink network at its UAS test site that will shortly transition to C-band.
The Choctaw Nation in Oklahoma under an FAA program seeks to enable BVLOS operations through a C-band C2 network.
New Mexico State University will use a Skylink C2 network around Las Cruces airport for small UAS (sUAS) operations and testing to overcome anticipated interference from nearby Air Force and Space Force operations.
The Tillamook UAS test range in Oregon has already installed the first ground site of a SkyLink network.
The University of Alaska at the Fairbanks UAS test site will use uAvionics radios for testing large, heavy UAS operations.
In Canada near the Jonesburg airport, a Skylink C2 network will support the safety case for BVLOS pipeline inspection operations for the oil industry.
While many of these new networks are not yet fully online, the use of frequency hopping, safety-monitored C-band, and certifiable transmissions for UAS command and control appears to be moving forward rapidly. Because the FAA is supporting this testing phase, it seems inevitable that large-scale C-band network rollout for UAS C2 will happen eventually.
5G phone networks, wireless UAS command and control, and aircraft safety systems essential for landing will need to find a way to co-exist and provide reliable, sustained service to their respective customer bases. Look for much more to develop in this ongoing tussle between industry groups and agencies who appear to have little in common, other than grudgingly sharing a crowded radio spectrum.

Its triple-redundant IMU includes three accelerometers, three gyroscopes, three magnetometers and three barometers. The hardware platform is designed and built to RTCA DO-254 DAL-C and meets rigorous DO-160G and MIL-810H power and environmental qualifications.
uAvionix Corp. has received a Technical Standard Order (TSO) from the U.S. Federal Aviation Administration (FAA) for its truFYX GPS receiver for unmanned aircraft systems (UAS).
Capable of receiving satellite-based augmentation system (SBAS) and wide area augmentation system signals, the receiver specifically targets UAS platform navigation and surveillance solutions.
With an increased regulatory focus on certifiability of UAS for beyond visual line of sight (BVLOS) operations, truFYX provides a critical component to enable safe navigation and airspace integration. A uAvionix’s blog article — “Why Certified GPS with Integrity for UAS Navigation Matters” — describes the importance of GPS receivers for UAS BVLOS operations.
The TSO-C145e Class Beta 1 GPS weighs 20 grams, which includes the receiver, antenna, DO-160G power supply and interface protection circuits. A Class Beta 1 GPS enables the truFYX to be the primary position source for domestic enroute and terminal navigation, as well as the primary position source for ADS-B OUT solutions.
The Source Integrity Level 3, System Design Assurance 2 system ensures reception and processing by Air Traffic Control and Traffic Collision Avoidance System when used as a position source for ADS-B. For these reasons, the Airbus Zephyr program was announced as a truFYX launch customer in January.
A certified position source for UAS navigation reduces position error by implementing a strict Receiver Autonomous Integrity Monitoring (RAIM) / Fault Detection and Exclusion (FDE) engine, and processing advanced SBAS messages designed to improve accuracy and integrity. These systems combine to detect unhealthy GPS satellite transmissions and remove them from the position calculation, providing critical differentiation from a typical commercial GPS receiver.
Design Assurance Level C software and hardware is achieved through the use of RTCA DO-178C and DO-254 engineering processes. As with all uAvionix TSO certified avionics, truFYX is manufactured in Montana under an FAA Manufacturing Inspection District Office approved quality-control process and facility.
truFYX technology has been previously TSO-certified in several form factors, including the highly integrated and complex skyBeacon, tailBeacon and tailBeaconX platforms.
uAvionix has added a new low-SWaP transponder to its line-up of unmanned aerial system (UAS) communications, navigation and surveillance solutions.
The ping200XR integrates the capability of the ping200X TSO Certified Mode S ADS-B OUT transponder with the high-integrity truFYX TSO-certified GPS position source into a single enclosure. The single enclosure simplifies installation and allows the customer to choose between the existing installed GPS antenna or one provided with the ping200XR.
The integrated GPS ensures maximum safety by providing Source Integrity Level (SIL) 3 RTCA DO-229D and TSO-C145e Class Beta 1 performance, a requirement for Mode S and ADS-B airspace access, and for reception and processing by certified avionics and Traffic Collision Avoidance Systems (TCAS) in other aircraft, as well as Air Traffic Control (ATC). SIL 3 performance is not available from non-aviation certified GPS, which are often used as an autopilot navigation source.
The ping200XR can be integrated with popular onboard UAS autopilots for dynamic control from ground-control stations, including George — uAvionix’s enterprise autopilot solution. The ping200XR can also be pre-configured before flight and carried as a payload.
Replicating the functionality of a cockpit transponder controller, the uAvionix mini-controller allows users to dial-in a squawk code before takeoff for even quicker integration and rapid deployment.
uAvionix Corp has launched its first autopilot for unmanned aircraft systems (UAS), named George.
At 80 grams, George is a low size, weight and power (SWaP) certifiable solution for enterprise operations and those wishing to type certify their UAS. It is manufactured in the United States.
Built around the open-source autopilot Cube from CubePilot, George combines Cube with Design Assurance Level C (DAL-C) hardware and safety and sensor monitoring, enabling customers to meet the type certification and safety case requirements for beyond visual line of sight (BVLOS) operations.
George’s triple-redundant inertial measurement unit (IMU) system includes three accelerometers, three gyroscopes, three magnetometers and three barometers, one of which has been TSO-certified under TSO-C88b in other uAvionix products such as skyBeacon, tailBeacon and ping200X. The hardware platform is designed and built to RTCA DO-254 DAL-C and meets rigorous DO-160G and MIL-810H power and environmental qualifications.
George is plug-and-play compatible with all of uAvionix’s certified and uncertified products, including
truFYX GPS (TSO-C145e)
ping200X (TSO-C112e, TSO-C166b, TSO-C88b)
RT-2087/ZPX-B (AIMS MkIIB)
pingRX Pro dual-band ADS-B receiver for detect and avoid
the microLink or SkyLink C-band command and control solutions
“The flight control capabilities of the Cube are superb, backed by hundreds of thousands of man-hours of engineering and experimentation over the past 10 years,” said Paul Beard, CEO of uAvionix. “But what has been lacking is a hardware platform that matches that capability in robust performance. George brings everything we’ve learned about certified avionics to the autopilot space in a way that outperforms existing enterprise and military autopilots in a lower SWaP package.”
George will be available for beta test-launch customers in June with production units available in the third quarter.
uAvionix first revealed this concept in a 2018 white paper titled “ADS-B Inert and Alert – A Solution to the ADS-B Spectrum Concerns.” The Inert and Alert Concept preserves spectrum by allowing the onboard UAS ADS-B solution to remain inert in a non-broadcasting listening mode until a safety-critical event such as a C2 lost-link or other aircraft proximity triggers it to begin broadcasting its ADS-B position as an alert. Once the conditions are safe again, the system reverts to its inert state.
“uAvionix is a firm believer in the benefits of a cooperative airspace for UAS integration,” said Christian Ramsey, president of uAvionix. “Recognizing the concerns by regulators of over-use of the spectrum, Inert and Alert is a means to leverage ADS-B for collision avoidance while significantly reducing those concerns.”

Upon tailBeaconX TSO certification, AV-30-C can double as tailBeaconX’s control interface, allowing the pilot to set the mode and squawk easily, while maintaining AV-30’s existing feature set. tailBeaconX with AV-30-C removes the need to drill additional holes in the airframe to satisfy requirements in countries outside the U.S. and keeps installation costs to a minimum.
“uAvionix is creating avionics with fundamental engineering advantages,” said COO, Ryan Braun. “These are beautiful, no-compromise certified avionics designed to deliver an affordable total cost of ownership. The AV-30-C provides an innovative probeless angle-of-attack and non-slaved directional gyro, both designed to dramatically lower the cost of installation without compromising performance. Where other avionics seem designed to be replaced, the AV-30-C will get better with age. We’re actively developing ADS-B In, electronic flight bag, transponder, and autopilot integrations to ensure AV-30-C becomes an indispensable instrument for every panel.”
AV-30-C will support third-party autopilot systems via the APA-MINI adapter, interfacing AV-30’s heading bug with legacy autopilots. The APA-MINI autopilot adapter is expected to be released in early 2021, with more advanced autopilot integrations to follow.
uAvionix has announced pingRX Pro, a detect-and-avoid ADS-B receiver for professional unmanned aircraft systems (UAS). PingRX Pro is expected to be available in the fourth quarter of this year.
pingRX Pro detects private and commercial aircraft operating on 978 MHz and 1090 MHz. The received aircraft’s identity, position and altitude are visualized on a moving map in real time, allowing the UAS operator or autopilot to remain well clear.
The new pingRX Pro continues uAvionix’s lineage of easy to integrate receivers with direct support for popular Ardupilot-based autopilot systems. By adding the protection of an aircraft-grade aluminum case and detachable remote mount antenna, pingRX Pro provides an ADS-B receiver for professional UAS operators who need performance, quality and flexibility for limitless UAS applications.
“UAvionix has led the way in ADS-B solutions for unmanned aircraft since our founding.” said Christian Ramsey, president of uAvionix. “Industry leaders and BVLOS operators continually choose ADS-B receivers as their primary detect-and-avoid solution. pingRX Pro now offers manufacturers and integrators the installation flexibility they need for their enterprise aircraft. ”
Weighing less than 8 grams, pingRX Pro features uAvionix ping ADS-B, proven in over a half-million ADS-B solutions worldwide, from UAS to airport vehicles to certified general aviation solutions.
PingRX Pro offers an external antenna, allowing operators to install it anywhere on the airframe. UAS are often designed from materials that can block radio frequencies and impair radio performance. By providing an external remote mounted antenna, performance can be maximized while providing critical protection of the receiver mounted inside the fuselage.
ADS-B Out
Diagram: uAvionix
ADS-B uses precision GPS information to broadcast the position of an aircraft in real time. The technology allows aircraft to share the skies more efficiently by telling each other where they are.
With ADS-B already widely adopted by manned aircraft, the task of detect and avoid is eased because the manned aircraft are broadcasting their position directly to the drone operator with no intermediary. While many aircraft not yet equipped with ADS-B OUT, nearly all large commercial operators are equipped.
The United States requires ADS-B OUT on all manned aircraft with an engine-driven electrical system operating near medium and large cities from the surface to 4,000 feet above ground.
Given the likelihood of ADS-B OUT on manned aircraft, and the density in these prime areas for inspection and package delivery, pingRX Pro ADS-B IN enables drone operators to meet their requirement to remain well clear of surrounding aircraft.
PingRX Pro tracks 100 simultaneous aircraft at ranges exceeding 150 miles, all at nearly 200% less power consumption of the alternatives.
